2-67.

Each part (a) through (d) below represents a different tile pattern. For each one, determine how the pattern is growing and the number of tiles in Figure 0. Homework Help ✎

• How many more squares does Figure 3 have than Figure 2?

• Make a slope triangle between two points on the graph to find the slope, or the growth rate.

• Growth rate: −2

1. $y=3x−14$

• Number of tiles in Figure 0: −14

1.  x −3 −2 −1 0 1 2 3 y 18 13 8 3 −2 −7 −12
• What is the difference between each y-value?
What is the value of y when x is 0?
